I am debating on building a stand for my 55g tank. The dimensions are 48 x 12 x 20. I want my stand to be 34 inches tall, but I don't know if the stand would be to top heavy. Does anyone have any suggestions on this? I plan on putting a 20-30 gallon sump in the stand also. If this is going to be to top heavy, is there a way to stablize it? Any drawings would help greatly as I am a visual learner.
